If I understand you right, you're saying "from GO (the mobile app) to PK7 (save)",
as opposed to GO -> GO Park (save) or GO -> Home -> save
If so, "integrating GP1 editor" and "removing GP1 entirely" would not deal with this.
And if so, you're out of your mind. Would require figuring out how to hack to GO (their servers) first.
Thus, unrelated to PKHeX until that time.
Until any external developers figure out how to hack into GO servers, what you're asking for is nothing short of magic.
that I agree with.
I actually had a response for something similar to this on the first segment of this post, but I shifted it down cause it is more appropriate here:
If you're asking for "recreation based on stats" type of thing, where you can just use stats from GO for PKHeX to recreate a mon,
then what I can say is: I am not sure what the summary screen shows on GO is enough.
Purely for the sake of accurate recreations: the height and weight there is truncated/rounded, you need to use another mobile app to figure out the level of the mon.
Whatever floats your boat, I guess XD
Though, I can see why gp1editor being merged into PKHeX would make the above be doable.
Except, I've got no idea how to program in C# (gp1editor was made in VB.net), nor do I know how to create a plugin for PKHeX.
Given such a thing isn't one of the features where the demand is a high priority, I'm not certain it'll get done. Well, one can dream (and request it)
As what was once mentioned for generation of legal PIDs for Gen 3/4 or handling of Gen 3 Mystery Gift importing, there's no need to add support for it when...
